This one had 2 alumunum lines running to it.. and once yanked, yup.. antifreeze.. not too much, the system was in real need of re-charge, when I pulled the AC pump, there was no pressure at all, just some dribble and a tiny hiss for about 3 seconds.

So I may have missed the heater core then. Bummer.. Would have liked to have seen what it looked like too. Honestly, I was in a bit of a hurry, had to get this thing in and be back to town before my son got off the bus, so next time, I'll just take one of these down to the firewall HA!
